End of the Line

He pulls the two fish from a refrigerator beneath a nearby
shed and lays them on the ground. The female, known as a
hen, glistens silvery in the wet grass, about 27 inches
long. She is a "bright" fish, Kirk explains, not long from
the sea. The other fish is smaller, darker, with a pinkish
lateral band that denotes a spawning male. Usually the
darker the fish, the less desirable to most anglers, though
Kirk seems pleased. I ask how long he fought them.

"I don't really know," he replies, "When you catch a fish,
time stands still."
Both fish have been fin-clipped; the brand they receive
from the hatchery. Wild steelhead populations have dropped
so precipitously that anglers are no longer allowed to keep
them but instead must release any caught unharmed. Unlike
salmon, steelhead can survive to spawn two or three times.
But steelhead favor similar spawning grounds as chinook and
coho salmon and, like these species, have suffered
dramatically from habitat loss and degradation. Young
steelhead spend up to three years in fresh water, so they
must have streams that are cool, well oxygenated and rich
in aquatic and terrestrial insects.
Logging hits them especially hard. Early loggers built
splash dams to help transport logs downstream, scouring the
streambed in the process. Modern clearcutting also destroys
riparian vegetation and shade trees, increasing the water
temperature and decreasing available food for young fish.
The ensuing erosion often buries spawning gravel with silt.
Two small creeks enter the North Fork not 100 yards from
Kirk's home, each draining separate draws in the mountains
beyond. In 1979 loggers clear-cut the south side and for
nearly five years, Kirk says, its crystal stream ran like
coffee. When it finally began to clear, the loggers cut the
north side and the second stream began pumping silt into
the river.
Kirk wants to show me a nearby hatchery, so we hop in the
car and follow a meandering one-lane blacktop that
parallels the river. Even in the cold rain, pickups are
parked at each bridge, while their owners wade into the
dark swirling water, casting continuously. At the hatchery,
tiny coho salmon, about three inches long, swim in a series
of narrow concrete tanks. They hit the surface like
raindrops when Bill and I walk by. That behavior is part of
their problem.
In the late 1930s when the first big dams were constructed
on the Columbia, Congress passed the Mitchell Act, which
funded the building of hatcheries to compensate for lost
habitat. At that time, fishery science was still evolving,
and hatchery managers naturally concentrated on stocks that
prospered in hatcheries, if not in streams. In many rivers,
including the North Fork, managers decided to replace wild
runs with hatchery fish, stringing an electric weir across
the stream to capture native spawners. The endangered Snake
River sockeye was the target of a similar enterprise in
Idaho.
